The present application describes providing an attestation level to a received communication. The attestation level may be used to communicate a level of security to a network or a called party that receives the communication. The attestation level associated with the communication may indicate to a destination network and/or recipient that the phone number associated with the communication is secure and/or the telephone number has not been spoofed.
